Definitions
- the present invention relates to a testability method in flight of an electronic power chain of an aircraft component.
- the invention also relates to an electronic control unit or electronic equipment integrating this electronic power chain of an aircraft component and this testability method, as well as to a nacelle and to an aircraft comprising the testability assembly. of the invention.
- An aircraft is driven by several turbojet engines each housed in a nacelle also housing a set of ancillary actuating devices related to its operation and providing various functions when the turbojet engine is in operation or stopped.
- auxiliary actuating devices may be for example a mechanical thrust reverser system or a variable section nozzle system.
- the role of a thrust reverser is, during the landing of an aircraft, to improve the braking capacity thereof by redirecting forward at least a portion of the thrust generated by the turbojet engine.
- the inverter makes it possible to return to the front of the nacelle all or part of the gas flows ejected by the turbojet engine, thereby generating a counter-thrust which is added to the braking of the wheels of the aircraft. .
- the structure of an inverter comprises movable covers movable between, on the one hand, an extended position in which they open in the nacelle a passage or a section for the deflected flow, and on the other hand, a retraction position in which they close this passage.
- These mobile hoods may furthermore perform a deflection function or simply the activation of other deflection means.
- the movable hoods slide along rails so that when backing up during the opening phase, they discover deflection vane grids arranged in the thickness of the nacelle .
- a linkage system connects the movable hood to blocking doors that expand within the ejection channel and block the output in direct flow.
- each movable hood pivots to block the direct flow and deflect and is therefore active in this reorientation.
- an aircraft comprises in known manner two electrical networks: a three-phase alternating electrical network delivering an alternating voltage called "high voltage", for example 115 Volts (115V) or 230 Volts (230V), and a continuous electrical network said " low voltage "delivering for example a DC voltage of 28 volts (28V).

- These different stages constituting the electronic chain are themselves controlled by a control electronics that can be integrated or not in the same housing as the power electronics.
- the electronics can also incorporate a function "BITE" (for "Built In Test Equipment") monitoring the system and used to detect certain failures of the control electronics and power.

- the permanent "non-availability", in flight, of this three-phase alternating network of the aircraft makes it possible to constitute one of the lines of defense imposed by the regulatory certification requirements.
- the 115V alternating network of the aircraft that powers the three-phase electric motor is available only when the aircraft touches the ground, thanks to a system called "Weight On Wheel” in English terminology, permitting the issuance of an alternating voltage of 115V to the electronic power trains driving the three-phase motors of the device actuating the thrust reverser as soon as said system has detected the contact of the aircraft with the ground.
- the actuator device of the thrust reverser When the aircraft has landed and when the pilot controls the deployment of the thrust reverser system, the actuator device of the thrust reverser is powered by the 115V AC mains; The control and power electronics of this device for actuating the thrust reverser can then deliver the electric current necessary for driving the electric motors, which motors causing activation of the actuators ensuring the deployment or retraction of the cover (s) of inverter.
- the pilot In the event of a malfunction of the electronic power train of one of the actuators of the thrust reverser device, the pilot detects this failure only when it controls the deployment of the reverser, ie on the ground, when the plane landed.

If the permanent magnet synchronous machine 300 has for example a short circuit-type fault, the current measurement of the DC bus 141 would have a significant value, therefore, greater than a predetermined threshold value. Similarly the measure of DC bus voltage would be virtually zero, therefore less than a pre-established threshold value.

For that, the testability method 500 analyzes measurements 150 after injection of test stimuli 140 and compares them with pre-established threshold values 160 to constitute a set of authorizations 161 and prohibitions 162.
- the non-functional status sanction 595 is established if at least one failure is detected by the testability method that is to say if at least one prohibition 162 is present.
- the functional status sanction 590 is established if no prohibition 162 is established, that is to say if no failure is detected during the test.
